Hubbard, Beverly, Mass, assignor to United Shoe Machinery Corporation, Paterson, N. J a corporation of New Jersey Application December 30, 1937, Serial No. 182,561 5 Claims. (Cl. 12-127) This invention relates to shoe machines and When pressure is applied to the shoe by move particularly to a work rest or support and is ment of the abutments l2, IS, the pad l conillustrated as embodied in a toe rest for engaging forms to the shoe bottom and applies pressure the forepart of a shoe such as is employed in mato the sole and causes it to be attached to the '5 chines for cement-attaching soles to shoes, a mashoe. The toe rest of the present invention, as

The rear wall of the casing is made somewhat concave forwardly at 36 and the pad 28 is upwardly concave in the region indicated at 38, making this part of the pad correspond more closely to the shape of the last at the throat portion of the shoe which it engages.

The shoe-engaging face of the pad 28 is made flat or slightly convex over a large part of its area so that as pressure is applied it will begin at the pad and be gradually extended toward its sides. The corner between the sides of the pad and its work-engaging face is rounded so that when heavy pressure is applied to the pad the area of pressure does not stop abruptly at an the pressure is applied.

Since the pad fits the casing, only the portion of the pad which extends beyond the casing is subject to deformation by pressure and hence the deformation of the pad may be controlled by pro- Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A toe rest for shoe machines comprising a casing having side walls, a rubber pad fitting the casing and extending beyond the walls of the casing, and means located in the casing between said side walls for holding the pad in place against accidental removal but permitting it to be removed at any time by a pull applied thereto.

2. A toe rest for shoe machines comprising a casing having side walls, a rubber pad fitting the casing and partially enclosed by said side walls, and a ball-ended stud extending into the casing and into a complementally shaped opening in the rubber pad to hold the pad detachably in place.

3. A toe rest for shoe machines comprising a on a last; the pad being unsymmetrical with respect to the longitudinal median line of the last and providing a and a casing confining the major portion. of the pad.

4. A toe rest for shoe machines comprising a casing having side walls, a rubber pad fitting the casing and extending beyond'the walls of the casing, means in the casing extending into the pad for holding the pad in place against accidental removal but permitting it to be removed at any time by a pull applied thereto, and a cover for the pad, the marginal portions of the cover being reduced in thickness and secured to the pad between the pad and the side walls of the casing.

and having its marginal portions secured to the pad and located between the sides of the pad and the walls of the casing.
